DOOR-HANGER.

SPECIFICATION forming part of Letters Patent N o. 394,317, dated December 11, 1888.

Application led May 24, 1888.

To @ZZ whom t may concern.'

Beit known that I, GEORGE \VARNER, of Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Door-Hangers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in that class of hangers for slidin doors in which the axles of the wheels or rollers which run upon supporting-rails above the door are adapted for independent vertical adjustment with relation to the top of the door to enable the doors to be accurately adjusted in hanging them.

The invention consists in the matters here inafter described, and pointed out in the appended claims.

In the accompanying drawings, illustrating' my invention, Figure l is a view showin g the upper part of a door and one track-rail, with the hanger in side elevation. Fig. 2 is aplan view of the parts shown in Fig. l. Fig. 3 is a transverse section taken upon line 3 3 of Fig. l. Fig. 4is a similar section taken upon linge 4 4 of Fig. l. Fig. 5 is a perspective view of the rider-bar detached 'from the other parts of the apparatus. Fig. 6 is a perspective view of the plate which is attached to the door. Fig. 7 is a perspective view of the link by which the rider-bar is connected with the door.

As illustrated in the drawings, A indicates the door, and B B two horizontal parallel track-rails located above the same, said rails having a space between them through which the hanger passes in the movement of the door.

C C are the wheels or rollers, which rest and roll upon the track B B, and which are rigidly connected with eachother by a cylindric axle, c.

D is a plate which is secured to the top of the door by screws or otherwise.

E is a second plate adapted for detachable connection with the plate D, the means of attachment herein shown consisting of a longitudinal dovetailed rib, e, upon the said plate E engaging a dovetailed groove, d, in the plate D.

F is a rider-bar, which is arranged above and parallel with the plate E, and the lower edge of which rests upon the axle c of the rollers C C. Said axle moves or rolls along the riderbar when the dooris moved, thereby giving rolling contact only between the wheelaxle and hanger in a manner heretofore co1nmon and well known. Said rider-bar is connected at one of its ends with the plate E by means of a link, G, connected at its upper end by a pivot, g, with said rider-bar, and at its lower end bya pivot, g, with the plate E, said pivot passing through upwardly-extending lugs e e upon the said plate. Said rider-bar F is herein shown as provided with a rightangled depending projection, f, with which the upper end of the link G is connected, and which forms a stop to limit the move` ment of the axle c relatively to t-he bar. .This particular construction in the riderbar is not, however, essential, and a stop for the axle may be otherwise made and the link pivoted elsewhere to the end portion of the bar. At its end opposite the point of attachment of the link G the rider-bar F is provided with a downwardly-extending arm, F, t-he lower end of which is provided with two laterally-projecting lugs, ff, Figs. l and 4, which lugs are adapted to engage the inner surfaces of two curved prongsor guides, c2 e2, upon the plate E. The inner curved surfaces of the said guides e2 c2 are curved in an arc having a radius approximately equal to the distance between the pivots g and g', so that if the lugs f f are shifted along said guides said lugs will be carried approximately in the same curve as that taken by the pivot g at the rider-bar will thereby be moved through corresponding curved paths and to the same extent both horizontally and vertically, thereby retaining the said rider-bar exactly parallel with the bar E when moved in the manner described. The purpose of so shifting the rider-bar is to enable the vertical position of the same to be changed with relation to the top of the door in adjusting the door for opthe upper end of the link G, and both ends of IOO eration, it obviously being desirable that the rider-bar should remain accurately parallel to the top of the door when so moved.

As far as the general purposes of my invention are concerned, any suitable connection between the bar F and the door may be employed for shifting the bar and holding it in its changed position. In the particular construction shown a screw, H, engaged with a projection upon the door and with the downwardly-extending part or arm F', is used for this purpose. As a desirable construction in the parts when the screw His employed, these parts are made as illustrated in the drawings, and as follows: The said depending part or arm F,'which in the instance illustrated is inclined in the same direction as the link G, is provided with a slot or opening, f2, through which the said screw II passes, the screw having screw-threaded engagement with a nut, li, which rests in contact with the inner edge of the said arm F'. The said screw H passes through an apertured lug, I, of the plate D near the edge of the door, and the screw His provided with a head, 7L', which bears against said lug, the said head h', together with the nut 7L, serving to hold the rider-bar F in a desired position with relation to the door, it being entirely obvious that if the screw is turned to carry it farther through the nut 7i said nut and the arm F', against which it bears, will be drawn downwardly toward the lug I, and

the rider-bar thereby brought nearer the door and the latter elevated. By turnin the screw in a reverse direction the door will be allowed to deseen d, the said rider-bar obviously remaining accurately parallel with the door when thus shifted. The lug I is arranged ad-A jacent to the edge or margin of the door, and the screw-head h' is located in such position that a screw-driver may be easily applied thereto after the door is hung.

The shifting of the end of the rider-bar F in a curved path as the lugs f' f move along the `curved surfaces of the guides e2 will obviously produce a slight change in the angular position of the screw H, and to prevent the binding of said screw the aperture in the lug I is desirably made somewhat larger than the screw, and the nut 7L is tapered to an edge h2, affording a transverse bearing surface in alignment with the axis of the screw, said bearing-edge resting in notches f3 f3 in the arm F', Fig. 5. The lug I is herein shown as cast integral with the plate D, which is di- `rectly secured to the door.

It is not essential, as far as the features of novelty in my invention are concerned, that a separate plate, E, should be employed Ito support the lugs c e' and the guides c2 e2, inaslnuch as said parts last mentioned may be attached directly to the plate D or otherwise attached to or upon the door. The employ- .nient of a plate, D, secured to the door, and a separate plate, E, to which the working parts of the hanger are connected, is common and well known, and is merely used for convenience in hanging the door, the main parts of the hanger when this construction is employed being first placed on the rails with the plate E suspended below the same, after which the said plate E is slid endwise into engagement with the plate D, thereby enabling said parts to be easily and quickly connected.

I claim as my inventionl. A sli ding-door han ger comprisi n g a riderbar and link pivoted to the bar and to the door and a curved guide upon the door engaging said bar, the bearing-surfaces of said guide being curved in the arc of l a circle having a radius approximately equal to the distance between the pivots of said link, substantially as described,

, 2. Asliding-door hanger comprisingariderbar provided with a dependin arm at one end, a link pivotally connecting the opposite end of said rider-bar with the door, a curved guide upon the door engaging and guiding the depending end of said rider-bar, and means adjustably connecting the said riderbar with the door, whereby the latter may be shifted vertically with .reference to the door, substantially as described.

3. A sliding-door hanger comprising a horizontal rider-bar provided with a downwardlyextending arm at one end, a link connecting said bar with the door, a curved guide upon the door engaging the lower end of the arm, andan adjusting-screw engaged with a lug upon the door and with the said arm of the rider-bar, substantially as described.

4L. A sliding-door hanger comprising a riderbar provided with a depending arm, F', provided with laterallyprojecting lugs at its lower en d, a link pivoted to the said bar and to the door, two parallel curved guides engaging said lugs, and an adjusting device connecting said arm F' of the said rider-bar with the door, substantially as described.

5. A slidin g-door hanger comprising a riderbar provided with a depending arm, F', provided with a slot or opening, f2, a link pivoted to said rider-bar and to the door, a curved guide upon the door engaging the lower end of said arm F', a set-screw, H, engaging alug upon the door and passing through said slot f 2, and a nut, 7L, provided with a transverse bearing-edge engaging the said arm F', substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.
